com(4) over 115200 bps support

Hi! all,
I want tester for attached patch.
(This patch defines COM_16950 at head forcely. ;-)
16650 supports max 460800 bps. (perhaps ;-)
16950 supports max 921600 bps.
It support over 115200 bps with 16650 and 16950.
I tested on hpcsh with Bluetooth PCMCIA card included 16950. My card
establish for 921600bps to me.
I am not convinced of 16650 correctly supporting it. And, this patch
was did not work with 'st16650 broken fifo' on my sandpoint(KURO-BOX:
MPC8241 SoC).
I would test on my some machines at tonight. ;-)
Thanks,
